P600 Methods for Testing the Performance of LEV

P600 Methods for Testing Performance of LEV

A one-day P600 LEV course delivered as a Webinar (‘live’ using Zoom) or face-to-face (usually Leicester Hilton Hotel)

Payment not required at checkout as Invoices will be sent approx 5-6 weeks before the course.

This entry level course enables delegates to identify and correctly use appropriate LEV flow-visualisation and measurement techniques (LEV Test Instruments) ….. under  competent supervision.

The course focuses on the fundamentals of LEV systems; the standard component parts, measurement and testing techniques and equipment etc.

It provides delegates with the necessary skills and knowledge to improve their understanding of Performance Measurements in LEV – and for many – to act as a starting point in their progress with a career in LEV.

It does not confer ‘competency’ on the delegate to allow them to undertake stutory examinations and tests under CoSHH Reg 9.

In general terms – by attending this P600 delegates will gain knowledge and understanding of the:-

  • Basic components of local exhaust ventilation systems.
  • Methodologies for undertaking the performance testing of LEV equipment
  • Qualitative visualisation techniques (smoke release/’dust lamp’ etc).
  • Quantitative measurement techniques (anemometers, Pitot tubes etc).


Delegates wishing to attend P600Methods for Testing the Performance of LEV” Webinar/On-Line training course are expected to have some basic knowledge of LEV systems.

Who should attend?

Anyone wishing to progress in a career within the Local Exhaust Ventilation industry.  It is a foundation course but it is also an excellent introduction to LEV for anyone who has responsibility for operating or maintaining LEV systems and also for those who use and operate LEV as part of their work.

It is a therefore very beneficial foundation training course for anyone who requires an introduction to the basics of the Methodologies and Instrumentation required when Testing basic LEV systems.   

Often P600 is taken by newcomers to the field of LEV or by less experienced personnel as part of their progression towards a Level 4 qualification, eg P601P604 series).  

P600 is a Level 3 course.

Please note:  P600 success does not confer ‘Competency’ to be able to undertake CoSHH Reg 9 TEXTs unsupervised.

The P600 qualification may also meet some of the base requirements towards membership at the Society of Operations Engineers (SOE) and the Institute of LEV Engineers (ILEVE).

P600 LEV Course programme

Webinar/On-Line or Face-to-Face Presentation

  • Introduction to the basic components of local exhaust ventilation (LEV) systems (i.e. inlets, ductwork, air cleaners, air movers, ventilation hoods and discharges)
  • Demonstrate the use of smoke generators and/or smoke tubes to visualise air flows in and around LEV systems
  • Use of a dust lamp to visualise fine airborne dust
  • Using a pitot tube/manometer combination
  • How to carry out a Pitot tube traverse to determine static pressure (Sp), velocity pressure (Vp), and then calculate the velocity in a ducted ventilation system
  • Principle of operation of vane and hot wire anemometers
  • How and where to undertake measurements in relation to the inlets (hoods etc) of an LEV system
  • An introduction to the maths used in Level 4 courses (eg P601 and P602)
  • Chosing the correct test equipment to use and how to use them correctly


At the end of the day there will be a short Multiple Choice Questionnaire (MCQ) examination (no maths :-)) comprising of 20 questions (time allowed 60 mins).

The exam will be marked by BOHS and on satisfactory completion of the MCQ, BOHS will award a “P600 Course Certificate“.


£375 (+exam fee £70*) + VAT / delegate

* Exam Fees reviewed by BOHS Jan each year

Follow-on course

The P601 Thorough Examination & Testing of LEV Systems course is a natural follow-on from this course, as is the OXYL8 P602 LEV Design Training Course.

Success with OXYL8

We work very hard with all our students to try and ensure a pass ….. first time.  To assist we have comprehensive course materials and handouts, pre-course guides and support. Our pass rate is excellent!
